Paul has told the WWE’s official YouTube channel: "I have committed my life to becoming a WWE superstar. I’m not doing other opportunities.
"I got offered $15 million to fight Messi’s bodyguard. Super appetising. Super cool. But I’m a WWE superstar.
"I’m on a mission right now. And all while all that other cute ancillary stuff works for other people, I’m devoting my life to this. So I turned that down and I’m going to be the best that I can."
